Widex Evoke RIC 10 (ERBO Series): A Complete Product Description

The Widex Evoke RIC 10 ERBO series — comprising the ERBO 440, ERBO 330, ERBO 220 and ERBO 110 — is a receiver‑in‑canal hearing aid from the Evoke™ family, the world’s first platform to integrate live machine learning. The Evoke ERBO series is designed for individuals with mild to moderate hearing loss, offering a fitting range of 0‑90 dB HL across all four technology levels. It uses a disposable size 10 zinc‑air battery — the smallest battery size available — making the device exceptionally compact and discreet. The “RIC” form factor places the main body behind the ear, connected by an ultra‑thin wire to a receiver that sits directly in the ear canal, reducing the “plugged‑up” sensation and allowing natural low‑frequency sounds to pass through.

Important note: The Evoke RIC 10 ERBO series is a non‑wireless hearing aid. It does not include MFi, ASHA, or direct audio streaming from smartphones. There is no built‑in Bluetooth. All control is via the Evoke app (using acoustic signals) or an optional remote control (RC‑DEX). This model is designed for users who prioritise maximum discretion, long battery life from disposable cells, and the powerful machine‑learning personalisation of Evoke — without the need for smartphone streaming.

The Core Smart Technology: SoundSense Machine Learning

What truly sets Evoke apart is its SoundSense Technology, a machine‑learning platform that lives inside both the hearing aid and the companion smartphone app. Every time you use Evoke, it evolves — because it learns from the adjustments you make in different sound environments and applies that knowledge to similar situations in the future. This is achieved through two complementary features:

• SoundSense Learn – When you encounter a challenging listening situation, the Evoke app presents you with two alternative sound profiles (A vs B). Simply listen and select your preferred option. Repeat this process as many times as you wish, and the hearing aid gradually builds a personalised sound model tailored to your unique hearing preferences. The system uses anonymised data from users worldwide to continuously improve its recommendations.

• SoundSense Adapt – The hearing aid remembers every adjustment you have ever made and intelligently applies those preferences to new environments — even if you have never visited that particular location before. Your Evoke never forgets, and it constantly applies what it has learned to deliver better sound automatically, without any manual intervention.

Underpinning these features is the powerful Fluid Sound Controller, a dual‑core processing system that continuously analyses incoming sound and automatically adjusts multiple parameters — including variable‑speed compression — to preserve natural sound quality while reacting quickly to dynamic acoustic environments. The Fluid Sound Analyzer maps out your environment into distinct sound classes (quiet, speech in noise, party, traffic, music, etc.) and selects the optimal settings in real time.

Technology Levels: 440, 330, 220 and 110

The Evoke ERBO series is offered in four distinct performance levels. The number indicates the sophistication of the feature set, with 440 being the most advanced and 110 the essential entry level.

Widex Evoke ERBO 440 – Flagship Performance

The ERBO 440 is the most technologically advanced option in the Evoke RIC 10 line. It features 15 processing channels for exceptionally precise sound shaping and 11 distinct sound classes that automatically identify your listening environment – from quiet conversation to a crowded restaurant or music concert – then apply the optimal settings for each. The 440 includes HD Locator for channel‑specific directionality, dramatically improving speech intelligibility in challenging noise. Advanced TruSound Softener smooths out sudden impact sounds like a door slam or clanking dishes. Digital Pinna helps you locate and focus naturally on voices in front or behind by mimicking the normal effect of your outer ear. Speech Enhancer Pro reduces noise and enhances speech in real time. The ERBO 440 offers up to five listening programs and the most refined version of SoundSense Learn.

Widex Evoke ERBO 330 – Advanced Everyday Intelligence

The ERBO 330 offers 12 processing channels and a high degree of adaptability for most daily situations – from family gatherings to outdoor conversations. It retains HD Locator, Advanced TruSound Softener and Digital Pinna, but with slightly fewer fine‑tuning options than the 440. Users benefit from up to four listening programs and a highly effective version of SoundSense Learn, making it an excellent choice for active lifestyles.

Widex Evoke ERBO 220 – Solid Mid‑Range Choice

The ERBO 220 is a reliable option for users with quieter lifestyles or those who want core Evoke intelligence at a more accessible price point. It offers 10 processing channels, up to three listening programs, standard Speech Enhancer, and basic versions of wind and impact noise management. It does not include HD Locator or Digital Pinna, but still features the full SoundSense Learn & Adapt capabilities and the Fluid Sound Controller.

Widex Evoke ERBO 110 – Essential Smart Hearing

The ERBO 110 provides core Evoke sound quality with streamlined features – ideal for first‑time users or those who primarily need amplification in quiet to moderately quiet environments. It comes with 6 processing channels and up to three listening programs. While it lacks the advanced directionality and sophisticated noise management of higher levels, it still includes SoundSense Learn & Adapt, TrueInput technology (113 dB SPL input range), dynamic feedback cancellation, and variable‑speed compression. Users can still control the hearing aid via the Evoke app and benefit from the machine‑learning personalisation that makes Evoke unique.

The Size 10 Battery: Maximum Discretion

The size 10 battery is the smallest hearing aid battery available. It is ideal for keeping the RIC 10 as compact and discreet as possible. A single battery typically provides 3‑5 days of use depending on amplification demands and daily wearing time. Because the device has no streaming or wireless features, battery life is not reduced by Bluetooth activity. The hearing aid features a battery door that also serves as an on/off switch – open the door to power down the device, close it to turn it on. Audible low‑battery warnings (beeps or voice alerts) indicate when a replacement is needed. No charging equipment is required, making this model ideal for users who prefer simple, disposable battery operation.

Important note about the RIC 10 form factor: Due to the extremely compact size, there is no push button on the device itself. All program and volume adjustments must be made by your audiologist during fitting or via an external remote control (RC‑DEX) or the Evoke app (which uses your phone’s speaker to send acoustic control signals).

Features Common to All Four Levels

Across all technology levels, the Widex Evoke RIC 10 shares a robust core of essential technologies:

• SoundSense Learn & Adapt – Machine learning personalisation is available on all four levels, making even the ERBO 110 a “smart” hearing aid that improves over time.

• TrueInput Technology – An expanded input range of 113 dB SPL, handling very loud sounds without distortion while preserving soft sounds.

• Dynamic Feedback Controller – Fast, artefact‑free cancellation of whistling feedback, engineered to adapt and preserve sound quality.

• Variable‑speed compression – Automatically adjusts from fast to slow for consistent speech understanding and listening comfort at all input levels.

• ZEN Tinnitus Management – A built‑in tinnitus relief tool using soothing fractal tones, available on all levels.

• Telecoil – Connect easily to induction loop systems in theatres, places of worship and public venues.

• Widex Evoke App – Full control over volume, programs and personalisation, plus access to SoundSense Learn. The app uses acoustic signals (your phone’s speaker) to communicate with the hearing aids, so no Bluetooth is required.

• RC‑DEX Compatibility – A simple, compact remote control (small enough to be used as a keyring attachment) for changing programs and adjusting volume. Its battery lasts twelve months – highly recommended for users who prefer physical controls.

• TV Play 2 Compatibility – Direct stereo streaming of television audio to your hearing aids using the TV Play 2 device (sold separately), which transmits via 2.4 GHz.

• IP68 dust/water protection – The device is resistant to dust and can withstand immersion in water, making it suitable for active users.

What Is Not Included (Honest Disclosure)

The Widex Evoke RIC 10 does not include:

• Direct audio streaming from smartphones (no MFi, no ASHA, no Bluetooth)

• Hands‑free calling (you must speak into your phone during calls)

• Rechargeable battery (size 10 disposable batteries required)

• Push button on the device (requires remote control or app for adjustments)

• Advanced features found in newer families like Moment or Allure (no PureSound™ ultra‑fast processing, no AI Sound Assistant, no Digital Pinna – though the 440/330 levels do have Digital Pinna as noted)

The Evoke ERBO series is designed for users who want the intelligence of machine learning in the most discreet possible RIC form factor, without the complexity or cost of wireless streaming. It is an excellent choice for first‑time users, budget‑conscious buyers, or anyone who prefers the simplicity of disposable batteries and app‑based (or remote) control.

Physical Design and Customization

The Evoke RIC 10 is supplied in a standard beige colour. Other colour housing options are available with a delivery lead time of three weeks (as per the terms on page 2). Receivers come in different lengths and power levels (S, M, P, HP). The cost to customise HP receivers is already included in the RIC pricing. Due to the compact size, there is no push button – a removal handle (often transparent) allows for easy insertion and extraction.

What You Should Know Before Buying

The Widex Evoke RIC 10 requires professional fitting by an audiologist. In India, hearing aids are exempt from GST; however, accessories (TV Play 2, RC‑DEX, etc.) do attract GST. Warranty varies by technology level – please confirm with your provider. You will need to purchase size 10 batteries separately. An RC‑DEX remote is highly recommended if you want physical volume and program controls.

This model is best suited for users with mild to moderate hearing loss (up to 90 dB HL) who want a discreet, lightweight RIC with powerful machine‑learning personalisation, excellent natural sound quality, and no need for smartphone streaming.
